The n.m.r. signal of white phosphorus in some substituted benzenes and halogen-free solvents was measured. In both types of solvents the chemical shifts were caused mainly by van der Waals interactions. An average anisotropy term of +2.4 ppm was obtained for phosphorus dissolved in benzene derivatives. A possible use for the large solvent effects of white phosphorus is given.
